Hi,

I have a doubt.
I need to convert managed enum to unmanaged enum.

C#

enum class MANAGED
{
   TYPE1,
   TYPE2
}

C++

enum UNMANAGED
{
   TYPE1,
   TYPE2
}

I did the fillowing code

C++

UNMANAGED unman = (UNMANAGED)((int)man);

But i'm getting undefined value in the variable unman

Please reply....

Because your using MANAGED enum it will not be converted automatically to int so you should have:

C#

int temp = (int)man; //But "man" must be initialized!  
UNMANAGED unman = (UNMANAGED)temp;

Assuming the variable 'man is of Type MANAGED, and is assigned, this code will work:

C#

MANAGED man = MANAGED.TYPE1;
UNMANAGED un = (UNMANAGED)((int)man);

An obvious bug is your use of the word 'class here: enum class MANAGED.

This will work:

C#

MANAGED man = MANAGED.TYPE1;
UNMANAGED un = (UNMANAGED) man;

Because each Enum value has an intrinsic numeric value: conversion (to integer) is not required.
